In 1.2 you can find out how much memory a machine has by looking at Xen's boot output (tools/misc/xen_dmesg.py). The amount of memory is near the top, e.g.: (XEN) Initialised all memory on a 255MB machine If you run a later version of Xen there's also the physinfo stuff that Ian mentioned. I think there is already a very simple Python script that uses the physinfo op to get the number of CPUs, hyperthreading info, CPU speed, total physical memory and free physical memory.

It's in tools/misc/xen_log.c and AFAIK will only work on 1.2 and earlier. I personally haven't used it but it might be something like what you want. HTH.
